Application filed November 5, 1915.

To all whom may concern.'

Be it known that l-,zDANmL STERN, a subject of the King of Hungary, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented new and useful Improvements in Window- Screens, of which the following is a specification.

This invention relates to improvements in fly screens as applied to window openings of dwellings, offices and the like, and has for its principal object the provision of means whereby such screen may be readily placed in position or removed, being eXtensibly adjustable laterally, so as to suit any variation in the window width.

A further object is the provision of means whereby the screen may be swung outwardly from along its upper edge, or secured in a vertical position as may be preferred. And inally to provide such screens in forms cheap to construct, easy to operate and which will eifectually fulfil their purpose.

These objects are attained by the novel construction and combination of parts hercafter described and shown in the accompanying drawing, forming a material part of this specification, and in which Figure 1 is a partial front elevation of a window, showing the application of the invention. Fig. 2 is an enlarged horizontal fragmentary section taken substantially on line 2-2 of Fig. 4. Fig. 3 is a fragmentary front elevation, taken at the upper left hand corner of the screen, and Fig. 4 is a similar front view and section taken at the lower left hand corner, substantially on line 4 4 of Fig. 2.

In the drawings, the numeral 10 represents the sides of a window frame, 11 the sill thereof, and 12 the upper sash, which is adapted to slide vertically between strips 13 secured on the inner sides of the window frame and when raised in the -position indicated in Fig. 1, leaves an open space therebelow, in which the screen may be placed and secured in position.

The screen is comprised of a pair of vertical plates 15 positioned between the uprights 13 in place of the window sash, and having attached a pair of plates 16 arranged to extend inwardly the full height of the screen in parallel, as shown in Fig. 2. These plates are slotted horizontally, as at 17, and Slidable in the slots are pins 1S, provided Specification of Letters Patent.

with enlarged heads 19, the pins being normally pressed toward the center of the window space by means of the curved push springs 20, one of which is disposed upon the outer side ofv each plate 16.V The pins 18 are rigidly affixed in the vertical side members 22 of the screen frame, these members being movable between the plates 16 which act as lateral guides for them.

Adjacent to the inner edge `of the frame members 22 and secured by hinges 24, are bars 25 in which are clamped the lateral edges of the screen 26, which is provided at its upper edge with a stiffening bar 27, a similar bar 28 being at the bottom. Thus it is possible to swing the lower edge of the screen outwardly upon the hinges 24, at such times as may be desired, without affecting the position of the main frame within its seat between the window frames. At the opposite or lower end of theframe 22 is a catch 29 receptive of the hookelement 30, pivoted at 31, on the screen frame bar 25, whereby the screen is held in vertical position under normal conditions.

In operation, the lower sash being raised, one side edge of the screen is placed in position between the members 13 of the window frame, and pressure being applied upon the opposite edge, whereby the springs 30 are depressed and the plates 22 caused to slide laterally, the opposite side frame may be slipped into position upon the corresponding opposite side of the window frame, whereupon the springs exert Suthcient tension to hold the screen firmly in place; obviously, the frame may be removed by reversing the operation.

lf it be desired, to swing the screen outwardly, without removing it bodily, the hoolr 30 is disconnected from the catch whereupon the inner screen frame may be turned upon the hinges 24.

From the foregoing, it will be seen that this screen presents obvious advantages in being suited to a variety of different sized window openings, that it can be removed or replaced with the utmost readiness and that means are provided enabling the operator to reach articles outside the window without removing the screen from its position.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is z- 1. In an adjustable window screen, a pair of extensible lateral members, a screen frame hinged atthe top to saidmembers whereby it may beswung outwardly and means for securing said screen when in a normal vertical position.

2. In a Window screen, a pair of members disposable in the window frame having extending guides, a screen frame movable lat- Y erally between said 'guides, pins set in said Yscreen frame extending through slots in said guides,V Vand lsprings combined with said guidesexerting pressure on said pins whereby the screen 4is held centrally.

- 3. In a window screen, pairs ofguideA Y plates having horizontal slots near the top Copies of this patent may be obtained for DANIEL STERN.
